i am using node cron for running jobs , i am confused will this
pattern run every day including Saturday and Sunday as well
'00 00 22 * * *'
You have an entry too many in your cron expression.
It should be:
minute hour dayofmonth month dayofweek
Assuming you want to run at 10pm every day:
0 22 * * *
If you ever need to double check your cron expressions, I recommend using crontab guru

I am trying to get a cron expression through cron convertors online but it won't be able to do the same.
Some please help. I need a cron expression which should run every 3 hours starting at 00:10.
00:10
03:10
06:10
...
Also I need a cron expression that runs every 30 mins starting from 00:00.
00:00
00:30
01:00
...
something like this^
I tried
10/3 * * * *
and
*/30 * * * *
I need a cron expression which should run every 3 hours starting at
00:10
Simply with
10 0/3 * * * your_command
This way, the cron will run the specified command at 10 minutes past midnight (10 0) and then every 3 hours thereafter (0/3)
Also I need a cron expression that runs every 30 mins starting from
00:00
Then this might do the work
0,30 0-23/1 * * * /path/to/command
So it will run at 00:00 and 00:30 every day (0,30), every hour (0-23/1), and regardless of the day of the month, month, or day of the week (*)
The following cron expression cron(0 14 ? * MON-FRI *) basically runs something 4:00 pm from Monday to Friday.
I am wondering if it is possible to modify the expression so I can run something at 4:00 am and 4:00 pm every Monday to Friday.
Use this crontab line to run command_name at 4:00 and 16:00 (4 AM and 4 PM) Monday-Friday:
0 4,16 * * 1-5 command_name
From crontab manual:
The time and date fields are:
field allowed values
----- --------------
minute 0-59
hour 0-23
day of month 1-31
month 1-12 (or names, see below)
day of week 0-7 (0 or 7 is Sunday, or use names)
Your Cron job description looks different from the general crontab. But to give you an idea of how to achieve what you're looking for:
Edit cron-table. Choose your editor.
crontab -e
Add 2 lines cron jobs.
* 4 * * 1-5 /usr/bin/...# Your command goes here 04:00 am.
* 16 * * 1-5 /usr/bin/...# Your command goes here 04:00 pm.
4PM (16:00): 0 16 * * MON-FRI
See crontab guru
"At 16:00 on every day-of-week from Monday through Friday.”
4AM &4 PM (4:00 & 16:00): 0 4,16 * * MON-FRI
See crontab guru
“At minute 0 past hour 4 and 16 on every day-of-week from Monday through Friday.”
I got this crontab code to run a script on crontab every 15 minutes from 9 to 18 all days except weekends. However I would like to start fro 9:30 instead of 9. Is it there a way to do it?
*/15 9-18 * * 1-5
Using 30/15 in the minute area should work just fine:
30/15 9-18 * * 1-5
This will instruct crontab to run your script: “At every 15th minute from 30 through 59 past every hour from 9 through 18 on every day-of-week from Monday through Friday.”
I finally did this, and it works
30 9 * * 1-5
45 9 * * 1-5
*/15 10-18 * * 1-5
However, it needs three crontab entries.
i have a machine set in GMT.
i would like to have a cron task scheduled from 6AM to 5PM in PST, which is GMT-8.
gmt time zone. typical.
00 06-17 * * *
now -8 produces a crontab bad hour error.
00 22-09 * * *
the following is accepted or should i say, no error.
00 22,23,0,1,2,3,4,5,6,7,8,9 * * *
any short form therefore?
For vixie cron,
Lists and ranges are allowed to co-exist in the same field. "1-3,7-9" would be rejected by AT&T or BSD cron -- they want to see "1-3" or "7,8,9" ONLY
That is, the following:
00 22-23,0-9 * * *
You can try by changing the time zone for cron also:
suku#ubuntu-vm:~$ crontab -l | tail -2
TZ=Africa/Tripoli
* * * * * date > date.txt
suku#ubuntu-vm:~$ cat date.txt
Thu Jan 10 18:50:01 EET 2013
suku#ubuntu-vm:~$ date
Thu Jan 10 22:20:19 IST 2013
